kindly explain how you managed to solve the "scale" and ''departure" question without the calculator.
.the time one was easy i admit.
the latitude was given i guess N 43' 27'' and the dlong was approx 18'30'' with map distance of 10 inch.
lets assume the question wanted scale at N 27' 36''.
i was not able to solve the question without the calculator and have no clue how to solve it without one.
thanks.
